Constraints on Primordial Magnetic Fields from Planck combined with the South Pole Telescope CMB B-mode polarization measurements
Alex Zucca, Yun Li, Levon Pogosian
A primordial magnetic field (PMF) present before recombination can leave specific signatures on the cosmic microwave background (CMB) fluctuations. Of particular importance is its…
The long-term dynamical evolution of disc-fragmented multiple systems in the Solar Neighborhood
Yun Li, M. B. N. Kouwenhoven, D. Stamatellos +1
The origin of very low-mass hydrogen-burning stars, brown dwarfs, and planetary-mass objects at the low-mass end of the initial mass function is not yet fully understood. Gravitati…
POLARBEAR Constraints on Cosmic Birefringence and Primordial Magnetic Fields
POLARBEAR Collaboration, Peter A. R. Ade, Kam Arnold +84
We constrain anisotropic cosmic birefringence using four-point correlations of even-parity -mode and odd-parity -mode polarization in the cosmic microwave background measurem…
The dynamical evolution of low-mass hydrogen-burning stars, brown dwarfs and planetary-mass objects formed through disc fragmentation
Yun Li, M. B. N. Kouwenhoven, D. Stamatellos +1
Theory and simulations suggest that it is possible to form low-mass hydrogen-burning stars, brown dwarfs and planetary-mass objects via disc fragmentation. As disc fragmentation re…
Mass distribution and accretion of sub-halos
Yun Li, Houjun Mo
We use the "Millennium Simulation" to study the mass function of accreted sub-halos during merger events in the dark halo assembly history. Our study includes three kinds of sub-ha…
On Halo Formation Times and Assembly Bias
Yun Li, H. J. Mo, L. Gao
In this paper we use the ``Millennium Simulation'' to re-examine the mass assembly history of dark matter halos and the age dependence of halo clustering. We use eight different de…
